I use record using Audacity and when I go to playback it tells me that my sound card is already in use. Same thing when I try to use Jammit. I uncheck both boxes under sound exclusive mode. Then I change default playback from SPDIF to SPEAKERS and then sometimes it works. Then I go back from SPEAKERS to SPDIF and again it works sometimes. I have an X-Fi connected to my speaker via TOS cable. All my other sounds work. Gaming, music, and watching movies. I don't know what is using my soundcard that isn't allowing Audacity and Jammit to use it.
